剑道下拉小部件没有“占位符”属性。相反，您可以通过放置一个“optionLabel”属性，即

 var data1 = [ //this part is related to the above html tag
                 {text: "org1", value: "1", color: "#a8a9aa", selected:true },
                 {text: "org2", value: "2", color: "#000", selected: false },
                 {text: "org3", value: "3", color: "#000", selected: false },
                 {text: "org4", value: "4", color: "#000", selected: false },
                 {text: "org5", value: "5", color: "#000", selected: false }
            ];

   $("#inp1").kendoDropDownList({      
                  dataTextField : "text",
                  dataValueField: "value",
                  dataSource    : data1 ,
                  optionLabel   : "select your option",
                  select        : onSelect
           });

确保“onSelect”函数是在 JavaScript 中定义的。供引用check here .
